At the very heart of the XRS instrument is the microcalorimeter array. This is a very small detector, but it has unique and powerful capabilities. The final steps of its assembly are done in this laboratory right here. So let's go and see what all the fuss is about.

This is the XRS micro-calorimeter array. Essentially it's an array of very tiny thermometers designed to measure the temperature increase that occurs when an individual X-ray photon is absorbed.

This video clip shows Dr. Caroline Kilbourne explaining the XRS calorimeter array. This is an array of tiny calorimeters that is small enough to be held in the palm of a hand.
